Warning: We're upgrading the course to latest OpenXava version, unfortunately this lesson is not still upgraded. The lesson content is still valid, but maybe the source code for the example application needs some adaptation because previous lessons are already upgraded. The main change is the use of @ElementCollection for the detail lines of invoices and orders.
